2-Layer Flexible PCB - FPC Dhizaini uye Prototyping

Nhanganyaya

Flexible akadhindwa edunhu mabhodhi (FPCs) ari kushandura indasitiri yemagetsi, ichipa isingaenzaniswi kuchinjika uye dhizaini mikana. Sezvo kudiwa kwemamwe macompact uye akareruka emagetsi emagetsi ari kuramba achikura, maFPC anoita basa rakakosha mukugonesa gadziriso uye inoshanduka dhizaini mhinduro. Pakati pemhando dzakasiyana dzeFPCs, 2-layer inochinjika PCBs inomira pachena nekuda kwekuita kwavo kwakasiyana-siyana uye kushanda kwavo mune dzakasiyana siyana maindasitiri. Mugwaro rino rakazara, isu tichaongorora dhizaini uye prototyping maitiro e2-layer inochinjika maPCB, tichitarisa mashandisiro avo, zvishandiswa, zvakatemwa, uye kupera kwepasi.

Product Type:2-Layer Flexible PCB

A 2-layer flex PCB, inozivikanwawo seyakaviri-sided flex circuit, ishanduko yakadhindwa yedunhu bhodhi rine maviri conductive layer akaparadzaniswa neinochinjika dielectric layer. Ichi chigadziriso chinopa vagadziri vane kuchinjika kwenzira yekutevera mativi ese e substrate, ichibvumira hukuru hukuru dhizaini kuoma uye kushanda. Kugona kukwidza zvinhu pamativi ese ebhodhi kunoita kuti 2-layer flex PCBs ive yakanakira maapplication anoda yakakwira chikamu density uye nzvimbo inonetsa.

Applications

Iko kuita kwakasiyana-siyana kwe2-layer flex PCBs kunoita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa mumaindasitiri akasiyana. Imwe yeakakurumbira mashandisirwo e2-layer inoshanduka PCB iri mumunda wemagetsi emotokari. Muindasitiri yemotokari, nzvimbo uye uremu hwekuchengetedza zvinhu zvakakosha, uye 2-layer flex PCBs inopa kuchinjika kuzadzisa izvi zvinodiwa. Iwo anoshandiswa mumotokari dzinodzora masisitimu, masensa, mwenje, infotainment masisitimu, nezvimwe. Indasitiri yemotokari inovimba nekusimba uye kuvimbika kwe2-layer inochinjika maPCB kuti ive nechokwadi chekushanda kwakafanana munzvimbo dzakaoma.

Pamusoro pekushandisa mota, 2-layer inochinjika maPCB anoshandiswa zvakanyanya mumagetsi evatengi, zvigadzirwa zvekurapa, aerospace uye maindasitiri emidziyo. Kugona kwavo kujairana nemaitiro asina kujairika, kuderedza huremu uye kuwedzera kuvimbika kunoita kuti ive yakakosha mumhando dzakasiyana dzezvigadzirwa zvemagetsi.

Zvishandiso

2-Layer Flexible PCB Kusarudzwa kwezvinhu kwakakosha pakuona mashandiro ebhodhi, kuvimbika, uye kugona kwebhodhi. Zvinhu zvekutanga zvinoshandiswa kugadzira 2-layer inochinjika PCB zvinosanganisira polyimide (PI) firimu, mhangura, uye zvinonamira. Polyimide ndiyo substrate zvinhu zvesarudzo nekuda kwekudzikama kwayo kwekupisa, kuchinjika uye yakakwirira tembiricha kuramba. Copper foil inoshandiswa sechinhu chinoitisa, icho chine yakanakisa conductivity uye solderability. Zvishandiso zvinonamira zvinoshandiswa kubatanidza maPCB akaturikidzana, kuve nechokwadi kugadzikana kwemichina uye kuchengetedza kutendeseka kwedunhu.

Mutsara wakafara, mutsara wemutsara uye bhodhi ukobvu

Paunenge uchigadzira 2-layer inochinjika PCB, upamhi hwemutsara, mutsara wemitsara uye ukobvu hwebhodhi ndiwo akakosha paramita, ayo anokanganisa zvakananga kuita uye manufacturability yebhodhi. Yakajairika mutsara wakafara uye mutsara wemutsara we2-layer inochinjika PCB inotsanangurwa se 0.2mm/0.2mm, zvichiratidza hudiki hwehupamhi hwemafambisirwo ekufambisa uye nzvimbo pakati pawo. Aya zviyero zvakakosha kuti ive nechokwadi chekutendeseka kwechiratidzo, impedance control, uye yakavimbika soldering panguva yekuungana. Pamusoro pezvo, iyo bhodhi ukobvu hwe 0.2mm +/- 0.03mm inoita basa rakakosha pakuona kuchinjika, kubhenda radius uye yakazara ma mechanic properties ye 2-layer flex PCB.

Minimum Gole Saizi uye Surface Kurapwa

Kuwana chaiwo uye anopindirana gomba saizi kwakakosha kune 2-layer inochinjika PCB dhizaini, kunyanya kupihwa miniaturization maitiro emagetsi. Iyo yakataurwa yakaderera gomba saizi ye0.1 mm inoratidza kugona kwe2-layer flex PCBs kugarisa zvidiki uye zvakazara zvinhu. Pamusoro pezvo, kurapwa kwepamusoro kunoita basa rakakosha mukuvandudza mashandiro emagetsi uye solderability yePCB. Electroless Nickel Imersion Goridhe (ENIG) ine ukobvu hwe2-3uin isarudzo yakajairika ye2-layer inochinjika PCBs uye inopa yakanakisa kusakara kwekuora, flatness, uye solderability. ENIG kurapa kwepamusoro kunonyanya kubatsira mukugonesa zvakanaka-pitch zvikamu uye kuve nechokwadi cheakavimbika majoini ekutengesa.

Impedance uye Kushivirira

Mune yakakwirira-kumhanya yedhijitari uye analog application, impedance control yakakosha kuchengetedza chiratidzo chekuvimbika uye kuderedza kukanganiswa kwechiratidzo. Kunyangwe pasina chaiyo impedance hunhu hunopihwa, kugona kudzora iyo impedance ye2-layer flex PCB yakakosha kuzadzisa zvinodiwa nekuita kwemaseketi emagetsi. Uye zvakare, iyo kushivirira inotsanangurwa se ± 0.1mm, iyo inoreva kutenderwa dimensional kutsauka panguva yekugadzira maitiro. Tight kushivirira kutonga kwakakosha pakuita chokwadi uye kuenderana mune yekupedzisira chigadzirwa, kunyanya kana uchibata nediki-maficha uye akaomarara dhizaini.

2 Layer Flexible PCB Prototyping process

Prototyping inhanho yakakosha mu 2-layer flex PCB budiriro, inobvumira vanogadzira kuti vaone dhizaini, kushanda, uye kuita vasati vaenderera kuzere kugadzira. Iyo prototyping maitiro inosanganisira akati wandei akakosha matanho, anosanganisira dhizaini yekuongorora, kusarudzwa kwezvinhu, kugadzira, uye kuyedza. Kuongorora kwedhizaini kunovimbisa kuti bhodhi rinosangana nezvinodiwa uye kushanda, nepo kusarudzwa kwezvinhu kunosanganisira kusarudza iyo yakakodzera substrate, conductive zvinhu uye kurapwa kwepamusoro zvichienderana nekushandisa uye maitiro ekuita.

Kugadzirwa kwe2-layer inochinjika PCB prototypes kunosanganisira kushandiswa kwemichina yakasarudzika uye maitiro ekugadzira inochinjika substrate, kushandisa conductive mapatani, uye kuunganidza zvikamu. Maitiro ekugadzira epamberi senge laser drilling, yakasarudzika plating uye inodzorwa impedance routing inoshandiswa kuzadzisa inodiwa mashandiro uye maitiro ekuita. Kana iyo prototype ichinge yagadzirwa, kuomarara kuyedzwa uye kuisirwa maitiro kunoitwa kuti uongorore kushanda kwemagetsi, kushanduka kwemagetsi uye kuvimbika pasi pezvakasiyana mamiriro ezvakatipoteredza. Mhinduro kubva padanho reprototyping inobatsira dhizaini dhizaini nekuvandudza, pakupedzisira zvichizokonzera yakasimba uye yakavimbika 2-layer inoshanduka PCB dhizaini yakagadzirira kugadzirwa kwakawanda.

2 Layer Flexible PCB - FPC Dhizaini uye Prototyping Maitiro

Mhedziso

Muchidimbu, 2-layer flex PCBs inomiririra zvigadziriso zvemazuva ano zvigadzirwa zvemagetsi, zvinopa kuchinjika kusingaenzaniswi, kuvimbika uye kuita. Huwandu hwayo hwakasiyana hwemashandisirwo, zvigadzirwa zvepamberi, chaizvo zvakatemwa uye prototyping maitiro anoita kuti ive chinhu chakakosha muindasitiri yemagetsi. Sezvo tekinoroji iri kuramba ichishanduka, 2-layer inochinjika maPCB pasina mubvunzo ichaita basa rakakosha mukugonesa zvigadzirwa zvemagetsi zvinosangana nezvinodiwa nenyika yanhasi yakabatana. Zvingave mumotokari, zvemagetsi zvevatengi, zvishandiso zvekurapa kana aerospace, dhizaini uye prototyping ye2-layer inochinjika PCB yakakosha kutyaira inotevera wave yemagetsi innovation.
